How do bacteria get killed?

Sterilization or bacterial killing is brought about by many methods, such as physical methods, irradiation and chemical agents or disinfectants. Based on the availability of the method and the materials to be sterilized, we can choose which method to use.

Does bacteria die in boiling water?

Boiling water kills or inactivates viruses, bacteria, protozoa and other pathogens by using heat to damage structural components and disrupt essential life processes (e.g. denature proteins). … In water, pasteurization is reported to begin at temperatures as low as 131°F/55°C for protozoan cysts.

Can spoilage bacteria cause food to smell?

When food goes bad and starts to become pungent, it is most often due to the growth of spoilage microbes such as bacteria, yeasts and mold.
